This test method describes the measurement of the resistance of textile fabrics to bursting using the hydraulic diaphragm bursting tester.This test method is generally applicable to a wide variety of textile products.
Principle；
Sample is clamped over an expandable diaphragm. The diaphragm is expanded by fluid pressure to the point of specimen rupture. The difference between the total pressure required to rupture the specimen and the pressure required to inflate the diaphragm is reported as the bursting strength.
Significance and use:
This method for the determination of diaphragm bursting strength of knitted, non-woven and woven fabrics is being used by the textile industry for the evaluation of a wide variety of end uses.
In cases where test results obtained using the procedures in Test Method D3786 have not been correlated with actual performance, Test Method D3786 is considered satisfactory for acceptance testing of commercial shipments of textile fabrics for bursting strength since the method has been used extensively in the trade for acceptance testing. In cases where disagreement arising from differences in values reported by the purchaser and the supplier when using Test Method D3786 for acceptance testing, the statistical bias, if any, between the laboratory of the purchaser and the laboratory of the supplier should be determined with comparison based on testing specimens randomly drawn from one sample of material of the type being evaluated.
Bursting strength tester is a device that is employed to discover the bursting strength of the fabric, leather, paper, as well as paperboard. It is widely accepted among various applications due to its sophisticated properties including its precise functionality, robust design, corrosion resistance, consistency and long lasting ability. bursting strength tester
